There are broadly four ways to get rid of a car in Ireland: trade it against something new, sell it privately, take a cash offer from a buying service, or put it into auction.
Most people default to whichever one they've done before, or whichever one is nearest. That's usually a mistake, because the gap between the best and worst option for a given car can run to four figures — and which one is best depends heavily on what you're selling.
This isn't a walkthrough of auction day. It's an honest comparison of the routes, so you can work out which one your car actually suits.
| Auction | Trade-in | Private sale | Buying service | |
|---|---|---|---|---|
| Typical return | Market rate, set by bidders | Lowest — priced for dealer margin | Highest, if it sells | Low to middling |
| Speed | Days | Immediate | Weeks, sometimes months | Immediate |
| Effort | Low — drop it in | Very low | High — ads, calls, viewings | Very low |
| Certainty of sale | High, re-entered free if unsold | Certain | Uncertain | Certain |
| You control the floor price | Yes, via reserve | No | Yes | No |
| Dealing with strangers | No | No | Yes | No |
| Payment security | Bank transfer, five working days | Offset against purchase | Your own risk | Usually fast |
Cars with limited private-buyer appeal. Commercials, higher-mileage vehicles, older cars, unusual specs, imports, non-runners and anything with cosmetic issues. Trade buyers in a hall will bid on cars that would sit on Done Deal for three months.
When you don't want the hassle. No photographs, no ad copy, no timewasters, no meeting people at your house, no test drives with someone you've never met, no arguments about the last €200.
When you want a floor but not a ceiling. A reserve price protects you from selling too cheaply, while bidding lets a genuinely desirable car go higher than you might have priced it privately.
When you're not sure what it's worth. Auction discovers the price for you. A hall of trade buyers competing against each other produces a real market valuation, not a guess.
When speed matters. Your car goes into the next suitable auction rather than waiting for the right buyer to happen along.
Being straight about this matters more than the sales pitch.
A clean, in-demand, well-documented car with a full service history will usually make more money in a private sale. If your car is the kind that gets ten enquiries in a weekend, you're leaving money on the table by selling it into the trade.
If you're buying another car from a dealer anyway, the trade-in figure comes with a VAT and negotiation dynamic that can make the net position better than it looks in isolation. Compare the whole deal, not the headline trade-in price.
If you need money today, a buying service or trade-in pays faster than the five working days after sale.
If you can't get the car to Naas, that's a practical constraint worth resolving before anything else.
The reserve is the minimum you're willing to accept. Your car will not be sold below it. This is the single most important decision you make, and it's where most sellers go wrong in one of two directions.
Set it too high and the car doesn't sell. It'll be entered into the next suitable auction at no extra cost, so you haven't lost money — but you've lost time, and a car that appears repeatedly starts to look tired to regular buyers.
Set it too low and you've capped nothing but your own return in a weak room.
If you're unsure what your car is worth, ask the sales team. They see what comparable cars are actually making week to week, which is considerably more useful than an online estimate. A valuation before you commit costs nothing.
One thing to be aware of: cars of a certain age, condition or mileage may be required to enter as No Reserve, meaning they sell to the highest bidder whatever that turns out to be. If your car falls into that category, you'll be told upfront — but factor it into your decision, because you're giving up your price floor entirely.
If bidding stops below your reserve, the car isn't sold. It becomes a provisional sale, and you'll be contacted to see whether you'd accept the highest bid.
You are under no obligation to accept. If the offer is too low, decline it and the car goes into the next auction at no extra cost.
This is worth understanding before you enter, because it's your genuine second bite. Sellers who leave a contact number and stay reachable on auction day get the chance to negotiate. Sellers who don't, don't.
Entry fee — €50 per entry, payable by cash, debit or credit card when you bring the car in.
Seller's fees — Deducted from the hammer price before payment. Check the current seller's fee guide so you know your net figure rather than the gross one.
Re-entry — Free. If the car doesn't sell, it goes into the next suitable auction at no additional cost.
When you compare auction against a trade-in figure or a buying service quote, compare net against net. The hammer price minus fees is what you'll actually receive.
Turning up short of documentation is the most common avoidable delay.
Two things to sort before you arrive:
Outstanding finance. Tell the sales team if there's any finance on the car. This is straightforward to handle when it's disclosed and a serious problem when it isn't.
Personal items. Clear the car out properly — insurance disc, glovebox, door pockets, and check the boot. Things get left behind constantly.
When you arrive, you'll complete an entry form describing your car. That description is read out by the auctioneer when the car goes under the hammer.
The information must be accurate. If any of it is incorrect, you can be held legally responsible for costs arising from the incorrect statement. This isn't small print — buyers bid on the strength of what's declared, and a car sold on a false description creates a real liability for the seller.
Declare known faults. A disclosed fault reduces what the car makes by a predictable amount; an undisclosed one can cost you considerably more than that.
Once the car is sold and payment has been received for it, you'll be paid within five working days by bank transfer — hammer price less seller's fees. Provide your IBAN when you enter the car so there's no delay at the end.
If the car doesn't sell, it's entered into the next suitable auction at no extra cost. You haven't lost anything except a week.
Auction is likely your best option if: the car is high-mileage, older, commercial, unusual, cosmetically imperfect, or simply hard to sell privately — or if you want a fair market price without the work.
Private sale is likely better if: the car is clean, in demand, well documented, and you have the time and patience to sell it properly.
Trade-in is likely better if: you're buying from a dealer anyway and the overall deal stacks up.
A buying service is likely better if: you need the money immediately and are willing to pay for that speed.
If you're weighing auction against the alternatives, the quickest way to make the comparison real is to get a valuation and put a number against it.
